Fullsize GM SUVs have a problem that's making owners sick

Some fullsize SUV owners are getting sick, thanks to a buffeting and vibration problem in 2015 model year examples of the Chevy Tahoe and Suburban, Cadillac Escalade, and GMC Yukon. According to owners' complaints to the National Highway Traffic Safety Administration, the issue can vary from an annoying vibration inside the cabin to an experience so severe that it leads to dizziness and headaches. General Motors is aware of the complaints, but the fix isn't so simple. According to spokesperson Tom Wilkinson to Autoblog, the company "has been tracking this issue for a while." The problem has a fairly low incidence rate, but when it does occur the issue can be "uncomfortable and annoying for owners." There's no precise cause for the issue, Wilkinson claims, and in some cases, simply balancing the tires or changing the door seals can make it go away. However, not all of the fixes are so simple. AutoGuide dug deep into the problem and discovered a GM preliminary information bulletin that advised dealers to remove the headliner and to check the roof's bonds to the bows that go across the vehicle. However, that document included a note that the solution might not entirely eliminate things. According to AutoGuide, adding Dynamat insulation to the roof sometimes helped the problem. A GM spokesperson also told AutoGuide the company fixed the problem at the end of the 2015 model year, and didn't go into any more detail. This roof issue seems linked to some of the worst droning in these SUVs. According to one complaint from a 2015 Suburban owner to NHTSA: "Roof will not remain attached to the roof bows. This causes the buffeting similar to a window being down when all are up. The results span from annoying to painful." A 2015 Yukon owner claims to have another alleged cause for the problem in a NHTSA complaint from February 2015. This person brought their SUV to the dealer seven times over the course of four weeks for vibrations. The dealer replaced the driveshaft, suspension components, and more, but nothing worked. According to an engineer to the service adviser: "In an effort to prevent roll overs, they designed the frame and body mounts too stiff. There are 40 engineers working on issues, they have no solutions that work across the board." Wilkinson told Autoblog that GM is working with customers on an individual basis to rectify things. Since these are newer vehicles, dealers should also fix the problem under warranty.

2023 Detroit Auto Show Editors' Rankings

The 2023 Detroit Auto Show was back in its traditional location, though in its fall spot in the calendar, and it was another pretty quiet event. By our count, only five new models, or model lines, were revealed and brought to the floor; all of which came from Detroit's own car companies. Still, some of them were quite significant, and the types were diverse. Naturally, we also had our favorites. So take a look to see how we ranked the reveals of the Detroit Auto Show. 2025 Cadillac CT5 View 15 Photos 5. 2025 Cadillac CT5 The refresh for the 2025 Cadillac CT5 is no great revelation, because it doesn’t have to be. An already solid, attractive design means only light tweaks were made to its appearance, and the new front fascia and redesigned lights just make the CT5 just that much more aggressive. So what was missing from the current model? Apparently, the answer was a gorgeous 33-inch curved LED display serving as both infotainment and instrument cluster. It has touchscreen capability to both the right and left sides of the steering wheel, and provides 9K resolution. Update some of the safety and driver assist tech, and — boom — the CT5 is properly modernized. Now bring on the updated Blackwing. –Senior Editor, Green, John Snyder 2024 Jeep Gladiator Live View 10 Photos 4. 2024 Jeep Gladiator Jeep carved out plenty of time for what is essentially a no-brainer mid-cycle refresh, but thereÂ’s one among us who is easily swayed: Me. I dumped the maximum number of points allotted on the 2024 Gladiator with only three words of explanation: "I like Jeeps." But this is kind of a big deal. The Gladiator pulled a lot of weight for Stellantis during the pandemic by providing an alternative to pickup buyers while Ram dealers were scraping the bottom of the supply barrel. To be fair, we're probably giving the Gladiator a bit of advance credit here for its promise to deliver a 4xe variant in 2025, but who else is talking about their PHEV pickup plans? Your move, Ford. –Associate Editor Byron Hurd. 2024 GMC Acadia AT4 View 17 Photos 3. 2024 GMC Acadia The 2024 GMC Acadia is the one reveal from this yearÂ’s Detroit Auto Show that was actually a totally new vehicle, and as far as three-row SUVs go, GMC aced it. The exterior has its own personality separate from its Chevrolet Traverse twin. Its AT4 trim is legit with more ground clearance, a torque-vectoring rear diff and sweet orange marker lights on the fenders.

A new report from UC Davis claims that a global expansion of public transit could save 1,700 megatons of carbon dioxide yearly and over $100 trillion by 2050. A "high-shift scenario" would be necessary, wherein governments invest in rail and clean buses, expand biking and walking infrastructure and shift focus away from projects that encourage car use. This shift to public transit would especially be important in the US, China and India. Read more in the press release below.
